Abstract (en)
[origin: WO2015017985A1] This invention provided an aqueous coating composition for metal surface pre-treatment comprising: (i) at least one organosilane with at least one hydrolyzable substituent; (ii) at least one water soluble and/or water dispersible silane-functional oligomer; (iii) at least one water-soluble compound of the elements Zr and/or Ti; The resultant sol-gel coating composition reveals an extended shelf life and after surface pre-treatment using the invented coating compositions the metal substrates have higher resistance to corrosion, humidity and solvent and at the same time have better surface conductivity and paintability.
